IMPROVEMENT IN HAND-STAMPS.

Specification forming part of Letters Patent No. 186,707; dated January 30, 1877; application filed January 16, 1877.

To all whom it may concern:

Be it known that I, HIRAM S. BLUNT, of the city and State of New York, have invented an Improvementin Hand-Stamps, of which the following is a specification:

Stamp-cancelers have been made with a hollow body containing ink, and a plunger or diaphragm to force out the ink; the device, however, is unreliable and likely to blot.

My invention consists in a stamp-canceler made with a tube containing ink, and a piece of sponge or other porous material at the end, that projects sufliciently to touch the stamp to be canceled when the instrument is pressed thereon, and is sufficiently elastic to yield in use, and thus supply, as required, the proper amount of ink to efiectually cancel the stamp.-

By this improvement the operator does not have to press the canceler upon an ink-cushion and then upon the stamp; hence, half the labor is saved, and the sponge or other porousmaterial is packed into the end of the reservoir sufficiently to properly regulate the amount of ink passing through the same to the impression-face.

In the drawing, Figure 1 is an elevation of said stamp 5 and Fig. 2 is a vertical section.

ing the ink-tube s, or the head A may be unscrewed for the same purpose.

I claim as my invention- The hand-stamp made with an ink-tube, s, a head or handle, A, and a filling of sponge or similar porous material at the lower end of the ink-tube, substantially as set forth.

In testimony whereof I have hereunto subscribed my name in the presence of two witnesses.

HIRAM S. BLUNT.
